Extended triggered position method and device

Abstract

An extended triggered location method and device is provided. The device includes the following: a location calculating unit to calculate location of the target terminal and determine the location information, and a third party location reporting unit to send the location information of the target terminal to the third party terminal periodically or only when the area triggered condition is sufficed. With the present invention, the third party terminal can obtain the location information of the target terminal periodically or receive the notice of the target terminal's entry into / exit from a target area, in accordance with the principles of periodical location or area trigger location. Thereby, the invention supplies new location service application and satisfies the subscriber's demand for different location service applications.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a continuation of International Patent Application No. PCT / CN2007 / 000875, filed Mar. 19, 2007, which claims priority to Chinese Patent Application No. 200610065534.8, filed Mar. 20, 2006, each of which is hereby incorporated by reference in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to the technical field of user plane-based mobile location service, and particularly, to an extended triggered location method and device.BACKGROUND OF THE INVENTION[0003]Secure User Plane Location (SUPL) is a user plane-based standard protocol, which is a communication protocol allowing a mobile phone user to communicate with a location server, e.g. SUPL Location Platform (SLP), to obtain the location of a mobile location SET.[0004]Generally, immediate SET location includes network-initiated location and SET-initiated location. Specifically, the network-initiated location refers to that a location request initiat...

AI Technical Summary

Benefits of technology

The present invention provides a triggered location method and device that can send the location information of a target device to a third party periodically or only when certain area event triggering conditions are met. This ensures that the third party can receive the location result notification of the target device in case of emergency and also enables area event monitoring tasks to be set for different devices of different persons so that when the area event triggering condition is met, the responsible person can receive the triggering notification and the location information of the monitored object. This enriches the applications of location services and can meet the demands of different users in a better way.

Problems solved by technology

However, the protocol currently doesn't support sending the location result periodically to the third party according to a request of the target SET or network or sending the location result to the third party only when a certain area event triggering condition is met.
